Potassium phosphonate grants a double nutrient action in phosphorus and

potassium. Foval is a potassium phosphonate based product with high water solubility and an efficient use in plant nutrition. It will be easily absorbed by the plant when applied foliar way. Once it is absorbed by the plant, it will be efficiently dispersed inside the tissues, due to their high systemic capacity.

The presence of ion phosphate activates the plant immune system against some infections with fungal origin, by promoting the phytoalexines formation.
This will help the plant face any pest attack and, specially, increase the resistance against Oomycete fungi infections.
